ArcGIS Help 10.1 - SearchNeighborhoodStandardCircular (arcpy)

摘要

SearchNeighborhoodStandardCircular 类可用于定义以下邻域搜索方法：经验贝叶斯克里金法、反距离权重法、局部多项式插值法和径向基函数插值法。

语法

SearchNeighborhoodStandardCircular ({radius}, {angle}, {nbrMax}, {nbrMin}, {sectorType})

参数	说明	数据类型
radius	The distance, in map units, specifying the length of the radius of the searching circle.	Double
angle	The angle of the search circle. This parameter will only affect the angle of the sectors.	Double
nbrMax	Maximum number of neighbors, within the search ellipse, to use when making the prediction.	Long
nbrMin	Minimum number of neighbors, within the search ellipse, to use when making the prediction.	Long
sectorType	The searching ellipse can be divided into 1, 4, 4 with an offset of 45º, or 8 sectors.	String
